<div class="content wysiwyg-content">
&gt;&gt;Which of the following statements are true? 
 
1) The Integer class has a String and an int constructor 
2) The Integer has a floatValue() method 
3) The wrapper classes are contained in the java.lang.Math package 
4) The Double class has constructors for type double and float 
 
 
Answer to Question 1 
 
1) The Integer class has a String and an int constructor 
2) The Integer has a floatValue() method 
4) The Double class has constructors for type double and float 
 
i was going through above question from following link 
 
<a href="http://www.jchq.net/certkey/0803certkey.htm" rel="ugc">http://www.jchq.net/certkey/0803certkey.htm</a> 
 
It is not clear to me. 
 
Can Integer class can take String argument. 
 
Any ideas, resources, links, sample code highly appreciated. thanks in advance.

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
